Insights

Optimizing parenteral nutrition (PN) in very preterm infants by starting a new standardized concentrated neonatal parenteral nutrition (scNPN) regimen earlier improved protein intake. This enhanced protein delivery reduced the incidence of hyperglycemia requiring insulin treatment in these vulnerable infants.

Area of Science:

  • Neonatalogy
  • Pediatric Nutrition
  • Intensive Care Medicine

Background:

  • Impaired early protein intake in very preterm infants is linked to growth failure and neurodevelopmental issues.
  • Standardized concentrated neonatal parenteral nutrition (scNPN) can enhance early protein delivery.
  • A modified scNPN regimen initiated within 4 hours aims to further improve very early protein intake.

Purpose of the Study:

  • To assess if a new scNPN regimen improves very early protein intake in infants <29 weeks' gestation.
  • To determine if this improved intake occurs without significant PN intolerance or complications.
  • To compare outcomes with a previous scNPN regimen.

Main Methods:

  • A cohort of 38 infants (<29 weeks' gestation) receiving the modified scNPN regimen (group scNPN2) was studied.
  • This group was compared to 38 infants receiving the original scNPN regimen (group scNPN1).
  • Data on nutrition intake, metabolic status, and infections were collected.

Main Results:

  • Group scNPN2 received earlier PN, resulting in significantly higher protein intake (15.3 g/kg) in the first 7 days compared to group scNPN1 (11.8 g/kg).
  • Calorie, lipid, and carbohydrate intake remained similar between groups.
  • The incidence of insulin-treated hyperglycemia decreased from 53% in group scNPN1 to 26% in group scNPN2.

Conclusions:

  • Earlier initiation of the modified scNPN regimen effectively increases protein intake in very preterm infants.
  • Increased early protein intake is associated with a reduced need for insulin to manage hyperglycemia.
  • The modified scNPN regimen appears safe and beneficial for very preterm infants.

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
Insulin Secretory Vesicles01:05

Insulin Secretory Vesicles

Insulin secretory vesicles release insulin to stimulate blood glucose uptake and regulate carbohydrate metabolism. When the blood glucose levels increase, glucose enters the pancreatic β-islet cells through glucose transporters. Once inside, glucose is metabolized through glycolysis, the citric acid cycle, and the electron transport chain, producing ATP. This increase in ATP concentration closes ATP-sensitive potassium channels, leading to depolarization of the membrane and the opening of...
Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...
Hyperglycemia01:29

Hyperglycemia

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
